Abstract
LaNiO3(LN) and BaTiO3(BT) thin film was deposited on Si(001) substrate by RF-magnetron sputtering. BT thin film was deposited at R.T. and tried to crystallize by post annealing. Crystallized BT was obtained in the annealing temperature range above 600°C. Relative permittivity of BT annealed at 600°C was obtained from 20 to 150 at respective annealing time.
